$25 TinyScreen is an OLED Display for TinyDuino Arduino Compatible Board (Crowdfunding)

Back in 2012, Tiny Circuits launched a Kickstarter campaign for TinyDuino, an Arduino compatible board that’s… tiny, based on Atmel Atmega328P, and supports tiny stackable shields in a similar fashion to Microduino (launched in 2013). The campaign was successful, and the company is now back on Kickstarter with TinyScreen, an OLED display that can be stacked on top of TinyDuino to create a smartwatch, a minuscule gamepad, smart glasses, and more. TinyScreen technical specifications: 96×64 OLED display, 16-bit color depth 0.96″ (24.4mm) viewable area Software controllable backlight (OLED brightness) Power down mode Four push buttons along the sides (connected to IO pins) SPI interface for display Power Supply – 3.0V to 5.5V operation (higher voltages supported with TinyShield power regulator) Power Consumption – 20 – 45mA max supply current (depending on brightness) Dimensions – 25.8mm x 25.0mm Programming of TinyDuino can be done through a web interface for Arduino called […]

Waveshare DVK512 Kits For Raspberry Pi Model B+ Include RTC, Sensors, LCD Display, and More

Beaglebone (Black) expansion boards are called capes, Minnowboard ones are lures, and Raspberry Pi model B+ add-on boards can be HATs (HArdware on Top). When I found a kit for the Raspberry Pi model B+ on DealExtreme, based on Waveshare DVK512 add-ons board I thought it might have found a Chinese HAT, but unfortunately it is not compliant with HAT board specifications as it misses an EEPROM,and the dimensions are not the correct one either. Nevertheless, the kit, as well as extra accessories such as a 3.2″ LCD display, can still be interesting. The kit on DX comes with the following items: DVK512 expansion board that connects to the 40-pin Raspberry Pi B+ header and features PCF8563 RTC chip with battery, an on-board USB to TTL chip for debugging via micro USB, a character LCD interface, connectors for modules connected via UART, SPIO, I2C or GPIO, various jumpers and user […]

Amazon Fire Phone Features a Camera Array for Dynamic Perspectives, and Firefly Real-Life Object & Audio Recognition

Amazon first phone has been rumored for a few months, and yesterday Jeff Bezos finally unveiled the Fire Phone powered by Qualcomm Snapdragon 800 processor @ 2.2 GHz, with 2 GB of RAM, a 4.7″ 720p display. It also supports 3G and LTE cellular connectivity, and beside a 13MP rear camera, and 2MP front camera, it also features a specialized camera array with four sensors to offer “Dynamic Perspective” and show different information depending on the position of the phone. Beside the hardware, the most notable feature is Firefly an augmented reality application that can recognize objects you may want to buy, and automatically link them to the Amazon store. Let’s go through the hardware specifications first: SoC – Qualcomm Snapdragon 800 quad core CPU @ 2.2 GHz with Adreno 330 GPU System Memory – 2GB RAM Storage – 32 GB or 64 GB Display – 4.7″ HD LCD display, […]

Renesas DevCon Extension Organizes Free One-Day Courses About IoT, Low Power, Sensors and More

I’ve just come across a YouTube video called Ultra-Low-Power Solutions for Wearable Technology and the ‘Internet of Things’ On Renesas channel. The video itself promotes Cymbet EnerChip Solid State Batteries and Kits, working together with Renesas MCUs, and the interesting part is that they’ll provide a free training session for the kit as part of Renesas Devcon Extension 2014. This is not a single event as you may think, but instead the company hosts one-day workshops in various cities in the US and Brazil covering various tracks all year long, as you can see in the simplified schedule below. RTOS & Middleware track is not available anymore, but you can still attend training sessions for Human Machine Interfaces, Low Power designs, the Internet of Things and Sensors. As an example, the following lectures are available for the Low Power track: Renesas Low-Power MCU Lineup (30 minutes) – Updated technology roadmap […]

$120 Raspberry Pi Bundle with LCD Display, Expansion Boards, Cables, and Accessories

Yesterday, Element14 has announced Wolfson Audio Card for the Raspberry Pi which adds multiple audio inputs and outputs to the low cost ARM Linux board, as it has been widely reported in the blogosphere. I’ve just mentioned it in case you missed it, as instead I’m going to write about a bundle with the Raspberry Pi Model B, lots of expansion boards, cables, and accessories such as a power supply, or a remote control that can be purchased for $120. It may not be useful if you only have a specific project in mind, but if you want to play around and interface with lots of different hardware, or even offer electronics lessons, it could be interesting. The complete kit includes: Raspberry Pi Model B with 512 MB RAM. Acrylic Case for RPi (not shown above) Expansions boards and modules: DVK511 Expansion Board with headers, jumpers, LEDs, and potentiometer 2.2″ […]
